Water type in Pokémon has the following key characteristics and weaknesses:
- Water-type moves are super effective against Fire, Ground, and Rock types.
- Water-type Pokémon are weak to Electric and Grass type moves.
- Water type moves are not very effective against Water, Grass, and Dragon types.
- When defending, Water Pokémon resist Fire, Water, Ice, and Steel type moves.
- Additional notes: Water type attacks gain power in rain weather and lose power in harsh sunlight. Some abilities and moves interact uniquely with Water types, like Freeze-Dry, which is super effective against Water types despite being an Ice move.
In summary, Water type's main weaknesses are Electric and Grass moves, which deal extra damage to Water Pokémon. Their main offensive strength is against Fire, Ground, and Rock types.
